With flash re-directors we will be able to select on certain areas of scene to illuminated, instead presenting blanket lighting for the entire picture. The patent allows for a movable light source, a lens that redirects a fixed light source, or multiple flashes, which can either be automatically aimed at certain elements of the picture, or controlled by the photographer.
Previously the company put improvement toward its iPhone range's photographic capabilities with the launch of the iOS 4.1 firmware, as the result, iPhone users can have high dynamic functionality.
